Title: Optical equivalence method
Inventor: MATSUI TSUTOMU
IPC: G11B7/005
Filed: 1994-12-28
Abstract: PURPOSE: To improve the resolution without reducing the converging diameter of a light beam and to attain a high-density recording by confining the phase difference of a phase base medium which generates the phase difference in reflected light in accordance with recorded information to <=180 deg. at the time of reflecting the light from an optical head. CONSTITUTION: A ZnS-SiO2 combined film as a protective layer 12, GsSbTe as a phase transition medium 13, ZnS-SiO2 as a protective layer 14 and Al or Si as a reflection film 15 are formed on a transparent polycarbonate substrate 11 in Fig. (a) of the phase difference type phase transition medium. The medium 13 forms marks 16 in an amorphous state and crystallizes the parts exclusive of the marks in a crystalline state. Fig. (b) illustrates a pit type optical disk structure. Pits are formed on the surface of a polycarbonate disk 17 and the surface of the disk 17 is coated with a reflection film 18 on which a protective film 19 is formed. When these media is irradiated with the light of the optical head from below, the light from the optical head is reflected by the reflection film 15 or 18, and the phase difference generated in the light becomes <=180 deg.C. The phase difference of the reflected light from the phase difference medium is optimized, thereby, the inter-mark distance is made small and a high-density recording is made possible.
